NFL quarterback grades
How this works
What the Margin Grade is
The points a quarterback adds per play. Every dropback counts (completions, incompletions, sacks, scrambles), plus his own designed runs and pass penalties he draws or commits. An interception costs a flat 4 points, and no single play counts for more than 4 either way.
- Game: that game. Live during the game, final the next morning.
- Season: the season so far, pulled toward 50 until he has about 100 plays, shown with an 80% range.
- Career: every play of his career, pulled toward 50 by 100 plays.
- Right now: how good he is now. Past seasons count less, a newcomer starts from his draft slot, and each game is adjusted for the pass defence he faced.
Chosen in a blind three-way study (Oct 2026): over ten out-of-sample seasons it tracked how many points an offense scored better than raw EPA per dropback and better than our earlier Skill and Form numbers. It describes how a quarterback played; it does not predict next season better than EPA per dropback does.
50 is an average quarterback play (2006-2021). One game's spread is about 25 points, so a 75 game is a very good one.
- Grade
- Margin Grade: the points a quarterback adds per play, season so far, pulled toward 50 until he has about 100 plays. The line is the 80% range and the tick is 50, an average play.
- Last game
- His most recent game. Italic with “few plays” under 10 dropbacks.
- Right now
- How good he is now: past seasons count about 45% less each year back, a newcomer starts from his draft slot, and each game is adjusted for the pass defence faced.
- Career
- Every play of his career, pulled toward 50 by 100 plays.
- Bad throws
- Bad throws per 100 charted throws (FTN charting, judged by hand). Fewer is better, so fewest first on the first click. Italic under 100 throws; a dash under 50. Shown for context, not part of the grade.
- G, Plays
- Games and plays the season grade rests on.
- CPOE
- Accuracy: completion percentage over expected, in points. It is quality, not style, so it sits in its own column and is not part of the Style column. Shown for context, not part of the grade.
- Style
- Two scales, each cut at that season's median among quarterbacks with enough dropbacks. Depth: how far downfield his throws go, from the average completion chance of his targets. Mobility: scrambles and designed runs per dropback. Downfield and mobile is a Playmaker, downfield and pocket a Pocket bomber, quick and mobile a Creator, quick and pocket a Rhythm passer. It is a scale, not a type: a quarterback near a line is marked close. Italic is an early read. Shown as a scatter in the player view, and left as a dash when the season has no style data yet.
Style is two axes, not four types. Each season, quarterbacks are split at the median on how deep their throws go and on how often they run, which gives four boxes. A quarterback close to a line could as easily sit in the next box, so he is marked close. Accuracy (CPOE) is shown on its own because it measures how well he throws, not how.
Click a column header to sort. Quarterbacks with at least 100 plays are ranked first; the rest are listed below them because a few plays says little. The By week view shows each game's own grade with his dropbacks under it; a game on fewer than 10 dropbacks is shown faded, left uncolored and sorted last. Switch to Season to date to see his season grade as it stood after each game instead. Single games swing far more than seasons do, so each week column is colored on its own spread.
